I get a good signal in one room in my house (15 foot seperation).
I bought it to send cable/dvr box signal to my screen room that is less than 75 feet from the transmitter and get
nothing but wavy lines with no audio, but I can change the channels.
I called X10 and they told me there is interference (no kidding) some type of electrical device in the path is blocking it
and I need to unplug the device or devices. That means I have to unplug the refrigerator, washer, dryer & A/C - furnace.
Come on X10 you advertised this is your best one yet and has invisawall technology, it's more like invisasignal!
